This dual-MCU repository features a heterogeneous architecture pairing an ESP32-P4 application processor with an ESP32-C5 Wi-Fi 6/BLE hub. Linked over a high-bandwidth 4-bit parallel SDIO interconnect, this design decouples heavy multimedia task execution from the networking stack to completely eliminate application interrupt starvation.
